bluefin

"Let's see what's out there." - Jean-Luc Picard

A familiar(ish) Ubuntu desktop for Fedora Silverblue. It strives to cover these two use cases. For end users it provides a system as reliable as a Chromebook with near-zero maintainance, with the power of Ubuntu and Fedora fused together. For gamers we strive to deliver a world-class Flathub gaming experience.

Documentation

For existing Silverblue/Kinoite users

1. After you reboot you should pin the working deployment so you can safely rollback.
2. [AMD/Intel GPU users only] Open a terminal and rebase the OS to this image:

Note: latest for current fedora, gts for current fedora - 1

Bluefin:

    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin:latest
    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin:gts

Bluefin Developer Experience:

    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin-dx:latest
    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin-dx:gts

1. [Nvidia GPU users only] Open a terminal and rebase the OS to this image:

   Bluefin:

    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin-nvidia:latest
    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin-nvidia:gts
   

   Bluefin Developer Experience:

    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin-dx-nvidia:latest
    sudo rpm-ostree rebase ostree-image-signed:docker://ghcr.io/bpbeatty/bluefin-dx-nvidia:gts
   

2. Reboot the system and you're done!

3. To revert back:

    sudo rpm-ostree rebase fedora:fedora/39/x86_64/silverblue
   

Check the Silverblue documentation for instructions on how to use rpm-ostree. We build date tags as well, so if you want to rebase to a particular day's release you can use the version number and date to boot off of that specific image:

sudo rpm-ostree rebase ostree-image-signed:docekr://ghcr.io/bpbeatty/bluefin:37-20230310

The latest tag will automatically point to the latest build.

Features

This image heavily utilizes cloud-native concepts.

System updates are image-based and automatic. Applications are logically seperated from the system by using Flatpaks, and the CLI experience is contained within OCI containers:

For Users

• Ubuntu-like GNOME layout
  • Includes the following GNOME Extensions
    • Dash to Dock - for a more Unity-like dock
    • Appindicator - for tray-like icons in the top right corner
    • GSConnect - Integrate your mobile device with your desktop
    • Blur my Shell - for that bling
• GNOME Software with Flathub
  • Use a familiar software center UI to install graphical software
• Built on top of the the Universal Blue main image
  • Extra udev rules for game controllers and other devices included out of the box
  • All multimedia codecs included
  • System designed for automatic staging of updates
    • If you've never used an image-based Linux before just use your computer normally
    • Don't overthink it, just shut your computer off when you're not using it

Frequently Asked Questions

What about codecs?

Everything you need is included. You will need to configure Firefox for hardware acceleration

How do I get my GNOME back to normal Fedora defaults?

We set the default dconf keys in /etc/dconf/db/local, removing those keys and updating the database will take you back to the fedora default:

sudo rm -f /etc/dconf/db/local.d/01-ublue
sudo dconf update
